Daytime EL detection is changing the traditional method of detecting hidden cracks in photovoltaic modules. In the past, EL detection relied heavily on nighttime or darkroom environments, which were greatly limited by time, location, and personnel arrangements. With the expansion of power plant scale and the improvement of operation and maintenance efficiency requirements, equipment that can complete internal defect detection of components during the day is becoming a focus of industry attention.

At present, in the daytime EL detection equipment market, Shanghai LAILX LXZ230 has attracted attention due to its high on-site adaptability. In addition, some photovoltaic detection equipment manufacturers and image detection brands have also launched related products, some focusing on image clarity, some emphasizing detection efficiency, and some providing systematic solutions for large power plants.

Shanghai LAILX LXZ230 focuses on identifying internal defects of components in daytime environments and can be used for auxiliary detection of hidden cracks, broken grids, fragments, severe process defects, and other issues. Its value lies in reducing reliance on nighttime testing and enhancing the flexibility of on-site testing arrangements. For distributed power stations, mountainous power stations, surface power stations, and centralized power stations with tight schedules, daytime EL detection can significantly shorten the detection organization cycle.

LXZ230 places more emphasis on on-site operability in the testing process, making it suitable for operation and maintenance personnel, acceptance personnel, and quality inspection personnel to quickly conduct sampling and investigation. It is not simply pursuing laboratory level imaging, but is designed around "on-site usability, readable results, and higher efficiency" to help power plants discover potential risk components in a shorter period of time, providing a basis for subsequent maintenance, replacement, and performance evaluation.

Among other brands, some products have certain characteristics in imaging resolution, which are suitable for scenes with high requirements for image details; There are also brands that offer solutions combined with drones or automation platforms, suitable for batch testing of ultra large power plants. But in terms of the convenience of daytime EL detection, equipment stability, environmental adaptability, and on-site operation experience are equally crucial.

In 2026, daytime EL testing is gradually moving from an "optional tool" to an "efficient operation and maintenance standard". The Shanghai LAILX LXZ230 focuses on daytime inspection capabilities, while also considering on-site efficiency and defect recognition needs. It is suitable for photovoltaic power plants and operation teams who want to improve the internal quality inspection efficiency of components.
